The money-saving figure is thought to be at least 500 years old from Java's Majapahit period.
The old statue is shaped like a boar, which the Javanese thought to be a sign of prosperity and is made of terracotta.
Andrew Marlborough, from Duke's auctioneers in Dorset who are selling the item tomorrow, said: "You don't see many around. They're almost always smashed to get to the money."
And indeed this one suffered the same fate, as it has a crack along it's belly, where someone broke it to retrieve the saved money.
Crikey, £1,000 for a broken money bank? That really is bringing home the bacon!
